Market Minute: Dell Earnings Tumble; Retailers Report Soft Sales

New concerns about the health of the bull market, and a big day for Dell. Those and more are what's in business news Friday

The Dow Jones industrial average (^DJI) tumbled 225 points Thursday, its worst loss in nearly two months. The Standard & Poor's 500 index (^GPSC) fell 24 points and the Nasdaq composite index (^IXIC) slid 63. The stock decline sent the yield of the 10-year Treasury to its highest level in two years.

A court hears arguments Friday on billionaire Carl Icahn's effort to block CEO Michael Dell from taking the company private. The stock is trading at about $13.75 a share, close to the price being offered by Michael Dell's buyout group.

Nordstrom's (JWN) earnings rose 18 percent, but its shares are set to fall. The upscale retailer lowered its forecast for the rest of the year. Meanwhile, shares of menswear retailer Jos. A. Bank Clothiers (JOSB) are set to tumble after slashing its earnings guidance.

Sony (SNE) has agreed to carry Comedy Central, MTV and other Viacom (VIA) cable channels on its planned Internet-based TV service. It's a big boost for Sony, which is racing against Google (GOOG), Intel (INTC) and others to secure content rights. Sony wants to use its PlayStation to provide an alternative to cable and satellite companies such as Comcast (CMCSA, CMCSK), Time Warner Cable (TWC), Dish Network (DISH) and DirecTV (DTV).

There's also a new competitor in the business to process mobile payments. Facebook (FB) will make it easier for its users to buy products when using the apps of its partner companies. EBay's (EBAY) PayPal unit and a division of Google dominate the field right now.

And Ford Motor (F) has reversed course. It will make a one-time payment of $550 to owners of its C-Max model, after lowering the advertised mileage on the hybrid by up to seven mpg.

Market Minute: Dell Earnings Tumble; Retailers Report Soft Sales

Mint made the Mac App Store's Best of 2012 list for a reason. This simple, clean app shows how much you are spending in each category of your budget by monitoring all of your transactions. We love signing in and getting a quick, dirty rundown of where our money has gone over the last week, and using their personalized budget tools to stay on track. We highly recommend adjusting your budgets for summer months. You might spend less on transportation when the weather is nice, and chances are you could use that extra cash to flesh out that restaurant tab, right?

This is the all-in-one financial organizer. Manage all of your accounts, from credit cards to magazine subscriptions, in one place and even make custom accounts for your rent or cleaning service. Get reminders for bill payments, and monitor all of your travel reward points, too. You'll always know what you owe, how much money you have and can plan for upcoming bills and expenses without having to sift through tons of paperwork.

If you want to isolate the expense tracker function of Mint in a super simple day-to-day app, then DailyCost is a great buy. A wide variety of categories lets users input all of their daily expenses. Holding your phone horizontally, you will be able to see graphs and statistics on your spending. The app also tracks your weekly and monthly spending by category and can be backed up to iCloud for Mac users, so you'll never lose your data.

If you're a heavy traveler, Toshl is an excellent expense and budget tracker. It works with any currency and lets you separate your travel budget from your day-to-day expenses. It comes with all the trappings of a regular money management app, too, such as bill organizer and alerts, and can be synced across all your devices.

Next time you organize a group activity, Tricount will split up the expenses for you. Create the expense report on your phone and organize by person, how much they owe, and then share via email so everyone knows their share. With options for expenses, balance, share, and configuration, the app does all of the math for you.

Never miss a bill payment again. This app reminds you when your payments are due, and lets you pay on the spot from a bank account or credit card, or you can schedule a payment for the future. Connect all of your accounts to the encrypted app and then view them all in one place for easy access and payment options. You'll never overdraft or miss a payment again.

Make and share payments with friends. This app uses the same technology to pay as LivingSocial, Uber and Airbnb. Pay with your debit card or transfer funds from a linked bank account, right to a friend's Venmo account. It is Verisign Certified.
